I have a table ,the definition is as follows：
class TEnterprise(Base):
__tablename__ = 't_enterprise'
__table_args__ = (
{'mysql_engine': 'InnoDB', 'mysql_charset': 'latin1'}
)
Fent_id = Column(String(32), primary_key=True)
Fent_type = Column(INTEGER(11), nullable=False)
Fcomb_cert_state = Column(INTEGER(11), nullable=False)
Fstate = Column(INTEGER(11), nullable=False)
Fbusiness_license_copy = Column(String(256), nullable=False)
Fbusiness_license_number = Column(String(32), nullable=False)
Fmerchant_name = Column(String(128), nullable=False)
Fsign = Column(String(64), nullable=False, server_default=text("''"))
the Fsign=md5(Fcomb_cert_state=${Fcomb_cert_state}&Fent_id=${Fent_id})
i can use context.current_parameters get the value of the field to be
updated, but how to get the value of the field that has not been updated,
thanks for help!
